Application filed March 15, 1912. Serial No. 683,984.

To all whom it may concern Be it known that 1, GRANT Srrr, a citizen ofthe United States, residing at Paterson, in the county of Passaic andState of New Jersey, have invented certain new and useful Improvementsin Driving Mechanisms for Winding-Machines, of which the following is aspecification.

This invention relates to winding machines of the kind in whichhorizontal thread-guide-carrying rails are reciprocated from leversarranged to oscillate in vertical planes parallel with the verticalplanes of the rails from a suitable rotating cam whose axis ishorizontal.

In the usual construction of this class of machines, the oscillatingmotion of the levers soon becomes very irregular, resulting not only inundue wear and tear on the parts but, what is of more importance,irregular conditions in the winding of the packages being produced. Thisis due principally to the fact that, however well the levers may befitted at their fulcrum-bearings and regardless of all effort otherwiseto prevent lost motion between any of the parts, the point of contact orbearing of each lever with the cam being offset relatively to itsfulcrum-bearing a torsion of the lever is produced which results inunequal wear at the fulcrum bearing, on the cam and the cam-engagingportion of the lever, and elsewhere.

My object is to construct the traverserail operating mechanism of amachine of the kind indicated so as not only to eliminate the cause ofthe torsional displacement of the levers but so as to hold each leverpositively against such displacement and otherwise kept true to the kindof movement it is intended to have.

A further object of the invention is to impart greater stability andrigidity to the framework or rigid part of such a mechanism.

In the accompanying drawings, Figure 1 is a side elevation of a part ofa winding machine improved according to this invention; Fig. 2 an endelevation thereof; Fig. 3 a plan view, partly in section; and, Figs. 4:and 5 are sectional views on lines 03-40 and y of Fig. 1.

The spools a on which the winding is accomplished are suitablv journaledin the frame I), resting on and being thereby driven from wheels 0 onthe shafts ol journaled in said frame, said shafts being suitably drivenand one of them driving the gear 6, fixed on a sleeve 7 journaled on ashaft 5/ projecting from the frame 6, through gearing it, all insubstantially the well known manner.

iis a cam of usual form, also fixed on said sleeve.

j j are the traverse rails sliding in the usual manner in the frame andeach having a vertically slotted extension 70.

At a suitable distance below the cam two forked brackets Z Z projectfrom the frame and on a pin m in each as a fulcrum-bearing is pivotallysupported a lever 72.

Each lever has secured therein a stud 0 on which is ournaled a roller 0'received by and playing in the vertical slot of extension 70, the rollerbeing retained on the stud by a cotter pin 0 each lever also carries abolt 29 secured in place by a nut 39 and on which is ournaled a flangedroller 2) (held in place by a cotter-pin 39) between the flange of whichand nut 79 the bracket la (receiving the roller in its horizontal slot1*) is received rather snugly. The power is transmitted to each bracketis (and hence to rail j) from lever n at 0 the parts 17' and 79 serve toretain the bracket is parallel with the lever, so that the rail j iskept true in its guiding means.

The acting face of the cam is the one appearing in elevation in Fig. 2.Usually the levers are made to engage the cam through the medium ofbearing-portions on the levers which project laterally (as seen in Fig.2, for instance), toward each other, from the levers, and this, underthe pressure of the usual spring 8 pulling the draft-bar t which looselyconnects the levers toward the frame, produces the undesirable torsionalready mentioned. Tn the present instance the bearing portion of thelever consists of a bracket to which is fixed to its narrow face (eachlever being flattened in the usual way) on the side thereof adjacent thecam and carrying a roller 0 which bears against the cam. The lever beingstraight as seen in Fig. 2, this construction brings its bearing-portioninto the plane in which the lever moves, so that torsional strain iseliminated.

Sidewise movement of the levers is pre vented by the brackets w, boltedto and projecting from the frame, the same having longitudinal slots 00in which the levers move, 3 being a roller revoluble in each bracket uand serving as an anti-friction device affording lateral support for thelever against the side of the slot w. Thus, even though the cam shouldwear a groove in the roller 2) (as in time it does), no side- Wisemovement being allowed, the cam runs continuously on the same part ofthe roller, occasionally rising to the high or unworn part thereof tovary the traverse of the rail at times and thus make the disposition ofthe windings irregular.

Rigidity and stability are imparted to the shaft 9 and the brackets w,and conse quently the moving parts which they sup- 'port and control aremaintained in a constant relation to each other, by the triangular brace2 which is rigidly secured by screws or otherwise to the extremities ofsaid shaft and brackets.

By my construction lost-motion and undue wear of the moving parts arereduced to substantially such a condition that they are practicallyinconsiderable, with the very important consequence that thereciprocating motion of the thread-guide-carrying rails has that uniformcharacter which is found indispensable in the regular and accurateplacement of the windings.

Having thus fully described my invention, What I claim as new and desireto secure by Letters Patent is 1. In a mechanism for reciprocating apair of traverse rails, the combination of the frame, levers fulcrumedin said frame on a horizontal axis, a rotary cam, a shaft projectingfrom the frame at right angles to the fulcrum axis of said levers andaffording a journal for the cam, said levers being held against the cam,a pair of brackets projecting from the frame and confining said leversto planes of movement each at right angles to the fulcrum axis of saidlevers, a brace tying the free ends of said shaft and brackets rigidlytogether, and means to rotate the cam, substantially as described.

2. In combination, the frame, a horizontal rail arranged to reciprocatetherein longitudinally, a rotary cam journaled in the frame, a levermember operatively connected With the rail and fulcrumed in the frame ona horizontal axis at right angles to the rail, a bracket projecting fromthe frame and having a slot parallel with the rail and receiving thelever member, rollers arranged at right angles to each other andjournaled in said lever member and one being received in andsubstantially fitting between the sides of the slot and the otherbearing against the am, means to urge the lever member toward the camand means to rotate the cam, substantially as described.

3. In combination, the frame, a horizontal rail arranged to reciprocatetherein longitudinally, a rotary cam journaled in the frame, a leveroperatively connected with the rail and fulcrmned in the frame on ahorizontal axis at right angles to the rail, a bracket projecting fromthe frame and having a slot parallel with the rail and receiving thelever, a bracket u attached to the lever, rollers journaled in thebracket u at right angles to each other and one being received in andsubstantially fitting between the sides of said slot and the otherbearing against the cam, means to urge the lever toward the cam, andmeans to rotate the cam, substantially as described.

4. In combination, the frame structure, a horizontal rail memberarranged to reciprocate therein, a rotary cam journaled in the framestructure, an upright lever member fulcrumed in the frame structure atone end and movable in a plane parallel with the rail, means to urge thelever member toward the cam, means to rotate the cam, said structureincluding means to confine the free end of the lever member to saidplane, and coupling means between the lever member and rail memberconfining the rail member to a plane parallel with the plane of movementof the lever member, said means including a vertical slot in one memberand a stud on the other member penetrating said slot and a horizontalslot in one member and a stud on the other member penot 'ating thel'iorizontal slot, one slot being arranged above the other,substantially as described.

In testimony whereof I atllix my signature in presence of two witnesses.
